Term millet cake needs to understand from geometry.This term is used to characterize point geometrically, and section reclines a face at that point.The vector perpendicular to section of millet cake, describes orientation at that point in such as by three-dimensional system of coordinate or the space that limited by other reference planes or the plane of reference, this face.

Because it is also millet cake under meaning of the present invention that each on face selects, so a mask has infinite many millet cake simultaneously.In order to describe the face of unidirectional or multi-direction bending in practice, but the millet cake of limited quantity is just enough.Term bend in one direction refers to face only bending along a direction on each point, such as cylindrical surface, and term multi-direction bending refers to face bending along multiple directions at least one point, such as spherical surface.

Flat face only has the section itself be harmonious with this face.Therefore a millet cake is just enough to the flat face of sign one, and at this, this millet cake can be any one point in this flat face.

Because millet cake is geometric point, so these millet cake are sightless on the whole.

Bright as before stated, be preferably be flat substantially by these driven surface zone design.This means, these driven surface regions have the flat region with substantially identical section, but these driven surface regions can be limited by the face etc. of edge, one-sided or many lateral bends, in other words can by edge or by the region transfers of arch in other regions of tool device.

The advantage in flat driven surface region is to provide such tool holding apparatus: this tool holding apparatus can not only make tool device pass through to design accordingly seamlessly to be received on the one hand, but also can by the forming surface contact in slave unit/transmission of torque region, between tool machine and the drive unit of tool device of corresponding tolerance and material behavior (such as elasticity etc.), this will expand the region that power is transmitted.

According to another preferred embodiment, driven surface region is bent at least partly.Can be no matter be the convex and spill with fixing or variable radius of curvature serves on unidirectional or two-way by this curved design at this.

This bending face also can be designed as, and they obey by the elasticity of its moulding and material the elasticity making to bend and change and make especially bending basic disappearance from certain load (namely substantially becoming flat driven surface region).

In a preferred embodiment, tool machine has at least one first coboundary plane and at least one second lower boundary plane in the scope in transmission of torque region.At this, these boundary plane are substantially perpendicular to driving turning cylinder.Preferably these two boundary plane are spaced apart from each other further.Preferably, each driven surface region is all arranged between a first coboundary plane and a second lower boundary plane, and exactly, preferred driven surface region contacts but do not intersect at each boundary plane.Especially, by arranging at least one driven surface region between these boundary plane, very large-area driven surface region can be obtained and correspondingly reduce the stress in this driven surface region.Preferably first group of driven surface region (at least one driven surface region) is arranged on one first between boundary plane and a second lower boundary plane, and preferred further second group of driven surface region is arranged between another the first coboundary plane and another the second lower boundary plane.Particularly by organizing into groups multiple driven surface region and attaching troops to a unit in boundary plane by this marshalling, the manufacture in transmission of torque region can be made on the one hand simple, in tool device, realize uniform especially torque on the other hand import.

In a preferred embodiment, multiple driven surface region extends between the first single coboundary plane and the second single lower boundary plane.Further preferably, all driven surface regions extend between the first single coboundary plane and the second single lower boundary plane.Particularly by making driven surface region extend between the first single coboundary plane and the second single lower boundary plane, low and essential material the is little in the fabrication process in addition transmission of torque region of space requirement can be obtained.Even more advantageously, particularly by this design to driven surface region, torque can not be delivered to tool device especially equably and therefore attacking material.

In a preferred embodiment, transmission of torque region has multiple driven surface region.Preferably multiple driven surface region is symmetrically arranged around driving shaft.

In the present invention, " around driving shaft Rotational Symmetry " refers to that described multiple driven surface region is by around at least one angle of drive shaft turns (this angle is greater than 0 ° and is less than 360 °) or rotate arbitrary angle, geometrically all overlaps with self.This angle equals 360 °/n especially, wherein n be greater than 1 natural number.

Particularly by this rotational symmetric setting in driven surface region, the additional stress on transmission of torque region can be reduced, make driven surface region load and particularly add service life thus equably in other words.

In a preferred embodiment, arrange to every two the driven surface regions of major general relative to a symmetrical plane symmetry.Preferably this symmetrical plane and an axial plane are harmonious.Preferably two or more, the driven surface region that is preferably four are arranged about a symmetrical plane symmetry.At this, driving shaft is particularly arranged in this symmetrical plane.Preferably these driven surface regions purlieu setting mutually substantially further.At this, the setting of mutually adjoining especially also should be understood to such setting in the present invention: driven surface region is connected to each other by transitional region.Preferably such transitional region can by bending extension or the region, face of smooth extension at least partly form.Further preferably, such transitional region is tangentially connected at least one, preferably on two driven surface regions.Especially, by this symmetry in driven surface region, the setting of mutually adjoining, transmission of torque region can be made to have extra high stability, and therefore realize the good power transmission to tool device.

In a preferred embodiment, transmission of torque region has sidewall.Preferably, this sidewall and driving shaft spaced radial are turned up the soil and are extended.More preferably, this sidewall extends between the first coboundary plane and the second lower boundary plane.Preferably this sidewall has driven surface region.Especially, by this design making transmission of torque region have sidewall, the basic recess for hollow taper is formed in the scope in transmission of torque region, but the recess of this hollow taper does not have circular cross section, but there is such cross section: in this cross section, sidewall is variable relative to the spacing of driving shaft in the plane orthogonal with driving shaft.Especially, by this design to transmission of torque region, transmission of torque region stable especially can be obtained, and therefore, it is possible in tool device, realize good torque importing.

In a preferred embodiment, sidewall substantially radial-sealing ground around driving shaft.In another embodiment, sidewall has recess or discontinuities on its route around driving shaft.Especially, by closed-loop around sidewall, particularly can realize transmission of torque region stable especially; By interrupt or the jagged sidewall of tool, transmission of torque region particularly can be made very light and there is minimum moment of inertia.

In a preferred embodiment, the normal vector in a section is orientated, radially away from driving shaft.It is pointed out that in this article at this, term normal direction and normal vector can be used in the same manner.Preferably, the normal vector in multiple section, preferred all sections is orientated, radially away from driving shaft.Particularly by this orientation in section, transmission of torque regional correlation is connected in axle in the past-hub and is presented as shaft portion.This design in transmission of torque region particularly can make manufacture simple, enables driving force be delivered to tool device from tool machine especially equably in other words.

Fig. 1 shows the schematic diagram of the tool holding apparatus 1 for the tool machine of manual guidance.Tool device 8 can be received on tool machine by this tool holding apparatus 1, and at this, tool axis of rotation and the driving shaft 2 of tool machine are harmonious substantially.Tool holding apparatus 1 is designed to, and when receiving tool device 8, handles locking device 5 by this tool device.This locking device 5 is designed to, and is remained on the position of opening by holding device 4.This holding device 4 is loaded by means of the direction of take-up device 3 along closing position on the position of opening.In this closing position, tool device 8 is received on tool machine, and is remained on tool machine by holding device 4.If when tool device 8 is taken out from tool holding apparatus 1, then during locking device 5 makes holding device 4 in an open position again, and when locking device 5 by tool device 8 by manipulation time, could again along the direction release holding mechanism of closing position.By this tool holding apparatus 1, can change tool device 8 when not having instrument on the one hand, this is such as common in the tool machine of manual guidance, can also complete tool changing simply especially on the other hand.

Fig. 2 shows two sectional views (Fig. 2 a is that Fig. 2 b is in open position in closing position) of tool holding apparatus 1.At this, the closing position of the Tool receiver 1 shown in Fig. 2 a refers to that holding device 4 is closed, and tool device 8 is received on tool holding apparatus.Open position shown in Fig. 2 b refers to that holding device 4 is opened, and tool device 8 can be inserted in tool holding apparatus, or is removed from tool holding apparatus.Tool holding apparatus 1 has take-up device 3, holding device 4 and locking device 5.Holding device 4 has two hook 4a/b that can move on the contrary.These hooks 4a/b is placed in tool holding apparatus rotationally by around common run-on point 4d.In order to retaining tool device 8, hook 4a/b has holding surface 4c respectively.Locking device 5 has the guide recess 5e of connecting rod shape, and in addition, locking device 5 and the first hook 4a single type ground are formed.In guide recess 5e, be bonded to motor element 6, and hook 4a/b is connected with take-up device 3 by locking device 5.Holding device 4 is maintained in closing position by take-up device.On open position as shown in Figure 2 b, motor element 6 is bearing in guide recess 5e.When being inserted in tool holding apparatus 1 by tool device 8, tool device contacts with hook 4a/b in the region of maneuvering area 4e/f.Contacted with this of hook 4a/b by tool device 8, apply torque thereon along the direction towards the closing position of hook, and start the closing course of tool holding apparatus according to the corresponding size of this torque.Can the hook 4a/b of reverse motions and the motor element 6 that can move in guide recess 5e by two, tool holding apparatus simple, safe especially can be realized with little component.

Fig. 3 shows a part for tool holding apparatus 1 as shown in Figure 2 with two detailed sectional views, and one is that (a), another is at open position (Fig. 3 b) to Fig. 3 in closing position.Motor element 6 moves along its direction of motion 6a based on the power effect brought by take-up device 3.Guide recess 5e is designed to, and in closing position, (Fig. 3 a) surrounds angle γ with direction of motion 6a to the normal 7a of the contact surface of guide recess 5e and motor element 6 ₂.On open position (Fig. 3 b), normal 7a and the direction of motion 6a of the contact surface of guide recess 5e and motor element 6 surround angle γ ₁.Angle γ ₂be selected as, it is in (preferably in the scope of 108 °-112 °) near 110 °, and the power that can adjust thus about hook 4a/b increases, and at this, power increase can cause the larger confining force of holding device 4.Angle γ ₁be selected as, it equals 180 ° substantially, is remained on open position by hook 4a/b thus.When applying torque by maneuvering area 4e/f by tool device 8 on hook 4a/b, holding device just can move away from open position (Fig. 3 b).Angle γ ₁and γ ₂size according to the given direction of motion of motor element 6, always can determine according to walking of guide recess 5e.By described to angle γ ₁and γ ₂selection, hook 4a/b can be made to be retained in safely on open position on the one hand, very high confining force (this confining force is put on tool device 8 by this hook 4a/b) can be realized on the other hand, and tool holding apparatus especially reliably can be realized thus.

Fig. 4 shows the detailed view being positioned at tool holding apparatus 1 in open position and closing position and locking device.This tool holding apparatus 1 has simple locking device 5, take-up device 3 and holding device 4.At this, Fig. 4 a shows tool holding apparatus 1, Fig. 4 b be positioned on open position and shows the tool holding apparatus be positioned in closing position, and Fig. 4 c shows the detailed view of locking device, and it comprises the mediate contact with lock face part 5a/b.Take-up device 3 pairs of holding devices 4 apply tightening force 3a, and pull to the direction of closing position.First lock face part 5a on open position (Fig. 4 a) contacts the second lock face part 5b, and based on tightening force 3a and and effective friction coefficient between these two part 5a/b obtain potential latching force (Sperrkraftpotential) 5d relatively.By tool device 8, the power effect reacting on this potential latching force 5d can be applied on holding device.When the power effect that this is derived from tool device 8 is greater than this potential latching force, holding device just can move along the direction of closing position (Fig. 4 b).In closing position (Fig. 4 b), by making the tightening force 3a on holding surface 4c be delivered to tool device 8, tool device 8 can be made to utilize holding device 4 to be maintained in tool holding apparatus 1.Fig. 4 c shows locking device 5, and wherein, the first lock face part 5a and the second lock face part 5b is contacted by intermediary element 5c.In order to make tool holding apparatus 1 enter into closing position from open position transfer as illustrated in fig. 4 c, and in maneuvering area 4a, apply power effect by tool device 8.When a threshold is exceeded, move in the direction along closing position (not shown) by holding device.

Fig. 5 shows two schematic diagrames of tool holding apparatus, and Fig. 5 b is in closing position, and Fig. 5 a is in open position.Tool holding apparatus 1 has take-up device 3, holding device 4 and locking device 5.Locking device 5 has the first lever element 10, second lever element 11 and Connection Element 12.At this, the first lever element 10 is connected with the second lever element 11 by Connection Element 12.First lever element 10 is applied in tightening force by take-up device 3 in closing position, and settles rotationally around run-on point d1.Second lever element 11 is settled rotationally around the second run-on point d2.Open position (Fig. 5 a) on, the first lever element 10 applies power effect F1 by Connection Element 12 on the second lever element 11.This masterpiece is spaced apart in order to spacing a1 and run-on point d2, and therefore on the second lever element 11, causes torque T1.If when tool device (not shown) is inserted in tool holding apparatus 1, then on the second lever element 11, cause power effect F2 by tool device (not shown) directly or indirectly.F2 is spaced apart with spacing a2 and run-on point d2 in this power effect, and causes torque T2 on the second lever element 11.If when torque T2 exceedes torque T1, then move in the direction along torque T2 by the second lever element 11, and tool holding apparatus will close.Under closure state as shown in Figure 5 b, the first lever element 10 applies power effect F3 by Connection Element 12 on the second lever element 11.F3 is spaced apart with spacing a3 and run-on point d2 in this power effect, and causes torque T3 thus.In this closing position, tool device (not shown) can be maintained in tool holding apparatus by holding device 4 (not shown).By the above, the design of lever element 10/11 and they are passed through to the connection of Connection Element 12, tool device can remain on so-called dead-centre position excessively, this mechanical mechanism is verified is ultra-safe, thus can realize the improvement to tool holding apparatus 1.

Figure 14 shows a kind of tool machine system, and this tool machine system has tool holding apparatus 1 and tool device 8.Tool device 8 is received on tool holding apparatus 1 like this: driving shaft 2 and tool device turning cylinder 8b are harmonious.Tool device 8 has tool interface region 8a, and this tool interface region extends between the first orthogonal plane 8c and the second orthogonal plane 8d.Tool drives face region 8f is arranged between the first orthogonal plane 8c and the second orthogonal plane 8d.First orthogonal plane 8c is along the direction of tool axis of rotation 8b towards the side Limit Tool interface area 8a of tool machine, and the second orthogonal plane 8d is at the side Limit Tool interface area 8a of tool machine dorsad.Tool drives face region 8f is designed to driving force to be delivered to tool device 8 from tool machine.For this reason, tool drives face region 8f has the cloudy shape (dienegativeForm) of driven surface region 9a at least partly, and can set up the connection of form fit thus between tool device 8 and tool holding apparatus 1.Tool device 8 has instrument code device 8e, and the first hook 4a of holding device 4 and the second hook 4b is engaged by this instrument code device.Hook 4a/b applies confining force effect 4h in the region of acting surface 4c on tool device 8.Tool device 8 is remained on tool machine by this confining force effect 4h.By the driven surface region 9a in transmission of torque region 9 with the dual-slant of angle [alpha] and β, tool device 8 seamlessly remains in tool holding apparatus 1.Indirectly confining force effect 4h is applied by take-up device 3.The hook 4a/b of holding device 4 settles rotationally around hook run-on point 4d.Take-up device 3 contacts with holding device 4 by motor element 6.By the described design of guide recess 5e, the summation of confining force effect 4h, is reinforced relative to tightening force 3a, and tool device 8 can be remained in tool holding apparatus 1 especially safely.

Figure 15 shows the trend of instrument sidewall 8i, and at this, this instrument sidewall has tool drives face region 8f.This tool drives face region 8f becomes and arranges around tool axis of rotation 8b with star, and with the driven surface region Local conjugation of transmission of torque region (not shown) arrange.Instrument sidewall 8i, in the scope of tool drives face region 8f, is extending relative between the first spacing r1 of tool axis of rotation 8b and the second spacing r2.Tool drives face region 8f has instrument millet cake 8h with regard to it.By the trend being matched with the driven surface region of transmission of torque region (not shown) of tool drives face region 8f, driving force form fit can be delivered to tool device 8 from tool machine, very large driving force can be transmitted safely thus.
